Usage notes

• In the standard language, when qualifying verbs, erioed is used with completed tenses in the past (present perfect, simple past, pluperfect), while byth is used with other tenses (present, future, imperfect, conditional).

Dw i erioed wedi bwyta bara lawr.

I've never eaten laverbread.

Dw i byth yn bwyta bara lawr.

I never eat laverbread.

• In some southern dialects, byth may be used colloquially where standard language employs erioed.

Sa i byth 'di byta bara lawr.

I've never eaten laverbread.

• With verbs negated by ddim, byth is usually found in post-subject position, where it replaces the ddim.
• Byth usually resists mutation but may be mutated in some cases, for example, optionally when folloqing the comparative degree of adjectives.

Dyna well byth/fyth!

That's even better!
